APPARATUS FOR ROLLING GLASS.

SPECIFlCATIONlfOrming part of .Letters Patent No. 6'?1,V17'5, dated April 2, 1901.

Application filed June Z6, 1900.

To @ZZ 1071/0712, it may concern:

Be it known that l, LEON APPERT, a citizen of the French Republic, residing at Paris, France, have invented a new and useful Improvement in Methods of and Apparatus for Rolling Glass, of which the following is such a full and clear description as willenable othi ers skilled in the art to make and use the istin'g between the `said table or roller and the uid mass of glass, or the sheet of glass is roughened, (unpolishedQpitted, and, as it were, marred `when this difference of temperature is small by reason of the impression made thereon by defect-s or faults which the surface of the said table or roller presents, however polished the latter may be at the moment of the` operation. i

My invention has for its object to diminish these defects and, if possible, to avoid them, and in order to attain this `the mechanical apparatus intended to effect the realization must satisfy the following conditions, to wit: that at the moment of rolling the same. point or any point of the duid mass shall not be in permanent contact with' the same point of the relatively cold surface of the roller or table employed for the rolling. In order to satisfy these conditions, the rolling apparatus is formed of two rollers capable of being cooled or otherwise, of as small a diameter as possible,and intended by their separation and the pressure which they exert to effect the rolling. A third roller of similar 0r larger diameter and formed of metal or of a suitable non-conducting material, placed in succession, is intended to receive the sheet of glass on its exit from the two lirst rollers and to opcrate the further conveyance of `the same withoutalteringoraffectingthesurface. This roller may be replaced by an inclined table forming a fiat surface constituted underthe conditions in which the roller hereinbefore Serial No. 21.681. (No model.)

mentioned is constituted and on which thc sheet of glass will slidegradually as produced, ln order to proceed to the rolling, the whole of these apparatuses are set inmotion, as in the ordinary manufacture by rolling; out in addition during the whole duration of the operation the rotating rollers are given, respectively and individually, a transverse reciprocatory movement at right angles to the rolling movement of suitable amplitude and equal to it and in the opposite direction, having for effect to avoid a permanent contact with the mass of iiuid glass before the latter is rolled and also with the glass at the very moment in which it is rolled in consequence of'their slipping on its surface, such slippingbeing produced without carrying the glass with it. The third roller, or the tablel which replaces it, has a similar reciprocating movement, which must be in an opposite direction to that of the lower rolling-roller. 'lhe table, or the roller placed in front of the rolling-out7 rollers, and on which the duid glass is poured, may be actuated so as to partici pate in this transverse reciprocating movement, it being alsoevident that each of the rollers or the table may have an independenttransverse movement, so as to be able to function alone or concurrently with the other rollers. rlhe movements ot these apparatuses maybe caused by mechanical means bggearings or otherwise and be interconnected or otherwise and combined with the rolling-out `movement proper.'

The accompanying drawings show an eX- ample of my apparatus.

Figure l is a View in front elevation of a machine by which the hereinbefore-specified conditionsof working maybe carried out, and Fig. 2 an end view of the same from the lefthand of Fig. l.

The same. reference-nn merals represent the same parts in both figures.

The rollers l and 2 are held in the ordinary manner in a frame having two uprights 3, and the rollers are arranged so that they may be moved apart or approachedone to another by means of anV ordinary system of tightening and regulating screws 4., according to the different thicknesses of the glass to be man ufactured. They are also arranged so that IOO the inclination as regards the horizon of a plane passing through their axes may in addition be varied as required. The driving of these rollers may be produced mechanically by means of gearings or the like. In the case shown in the drawings, 5 indicates the driving-shaft of the machine, actuated by a belt or directly by a dynamo. The movement is transmitted to lthe rollers l and 2 by means of pinions 6, 7, and 8. The reciprocating transverse movement is in connection with the rolling movement,and 1n ay be produced by means of grooved cams 9 and 10, fixed on the shafts 11 and 12 of the rollers 1 and 2, but at tbe opposite end from the pinions 7 and S. These cams 9 and 10, which are fixed on the shafts l1 and`l2, are each respectively in engagement with a fixed roller 13 14C, mounted on a fixed cross-piece 32 of the machine, and thus produce a transverse displacement of the cams, and consequently of the shafts of the rollers to which theyare fixed, and thereby also of these rollers themselves. A suitable arrangement of tongues and grooves must of course be provided to allow of this relative transverse displacement of the shafts and rollers, while permitting of their being carred around by the pinions 7 and 8.

In front of the rollers a casting-table 15 is arranged, having a suitable inclination necessary for the sliding of the material. Said table has a double formation, so as to allow of a suitable hot or cold liquid being circulated therein as required, and it has at the side two partitions, serving to keep the material in position. This table may slide transversely upon cross-bars 16 and 17, serving at the same time as strengthening-bars to the uprights of the frame and to receive a transverse movement or displacement by the action of a @am 18 with a roller 19, similar to the cams 9 and 10 and operated by a mechanical system of shaft and bevel-pinions 20 21 22 23 24E, this last pinion being mounted on the driving-shaft 5. A similar arrangement to that hereinbefore speciiied must be provided to enable the bevel-pinions to remain in engagement with the shaft 2O during the transverse displacements of this latter.

The sheet of glass after having been rolled is discharged from the rolling cylinders and received upon a table 25, similar to the casting-table 15, but having aslighter inclination. This table is supported by cross-pieces 26 and 27, on which it may slide, and-it may also have a transverse movement given to it by means of a mechanical arrangement of camshaft 28 and bevel-pinions 29 30 31 24, analogous to the one hereinbefore specified.

It is evident that the casting-tables and the tables for receiving the sheet of glass may be replaced by rollers of suitable dimensions, as has been hereinbefore specified.

The forms, proportions, dimensions, and accessory parts of my rolling apparatus may be varied and such materials be employed in its construction as may be deemed suitable.

I declare that what I claim is l. In apparatus for rolling plate-glass, a forming-roller, means for rotating the same, and means for imparting transverse Yor axial movement to said roller during its rotation.

2. In apparatus for rolling plate-glass, two juxtaposed forming-rollers, means for rotating the same, and means for imparting transverse or axial movements to said rollers during their rotation. l
